When a pattern a type do not match, opaque warnings were given precedence before structure mismatches. This is no longer always the case. Mentioned by Nick Marino on erlang-questions.

An opaque bug that would crash Dialyzer has been fixed. The bug was reported by Nick Marino.
2017-02-21dialyzer: Correct test cases after removal of erlang:hash/2Hans Bolinder
2017-02-20Add dummy end_per_suite/1Siri Hansen
common_test requires that if init_per_suite/1 exists, then end_per_suite/1 must also exist. If end_per_suite/1 does not exist, then it will be marked in the log as failed with reason 'undef'. Some test suites are corrected to avoid this.

2016-11-22dialyzer: Improve a warning messageHans Bolinder
Messages regarding guards with orelse/andalso could look like "Clause guard cannot succeed. The variable A was matched against the type any()". Now they look like as if or/and is used: "Guard test is_integer(A::atom()) can never succeed".
2016-11-22dialyzer: Improve a warning messageHans Bolinder
Messages like "Invalid type specification for function para3:exp_adt/0. The success typing is () -> 3" now look like "The specification for para3:exp_adt/0 has an opaque subtype para3_adt:exp1(para3_adt:exp2()) which is violated by the success typing () -> 3". The old message did not give any clue as to what invalidated the contract, namely the opaque subtype.
2016-11-22dialyzer: Correct a warnings messageHans Bolinder
Messages like "The attempt to match a term of type rec_api:f() against the variable _ breaks the opaqueness of rec_adt:f()" now look like "The attempt to match a term of type rec_adt:f() against the record field 'f' with type rec_api:f() breaks the opaqueness of the term".

2016-10-21dialyzer: Fix error handling of bad -dialyzer() attributesHans Bolinder
If a dialyzer module attribute references an undefined (local) function an error tuple is thrown but no caught. This leads to a 'nocatch' error and not the intended "clean" error.

2016-10-06dialyzer: Fix opaque bugHans Bolinder
The "decoration" of opaque types works better than before when opaque types are used by other opaque types.
2016-10-06dialyzer: Fix opaque bugsHans Bolinder
t_from_form() sometimes returned a more general type than it should have done due to a bug in from_form_loop(): it stopped when the limit was exceeded, which could mean a collapsed type. Returning a type with smaller depth should fix this. is_specialization() now handles opaque types before unions, which should fix another problem. The bugs reported by Kostis.
2016-09-26Use @ in variable names generated by core and kernelJosé Valim
The previous variable names can be generated by projects like LFE and Elixir, leading to possible conflicts. Our first to choice to solve such conflicts was to use $ but that's not a valid variable name in core. Therefore we picked @ which is currently supported and still reduces the chance of conflicts.

erl_bif_types:type/5 was calling erl_types:map_pairwise_merge/3 directly with its (potentially opaque) arguments, causing Dialyzer crashes. Bug (ERL-249) reported and minimised test case provided by Felipe Ripoll.
2016-08-31dialyzer: Increase time limit of suitesHans Bolinder
The test 'proper' takes some time.
2016-07-04dialyzer: Suppress warns on generated case stmtsMagnus Lång
Warnings about clauses that cannot match and are also compiler generated are suppressed unless none of the clauses return. This feature is useful for non-Erlang BEAM languages (such as Elixir) that compile to Erlang and expand certain language constructs into case statements. In that case, as long as the language construct can succeed, these warnings are undesired and appear spurious to users that do not check the Erlang code that their program expands into. Thanks to José Valim for the test (slightly modified).
